Kihwal Lee updated HDFS-5449:
-----------------------------
Attachment: HDFS-5449.trunk.patch
The new patch throws an IOException if ipAddr or xferPort cannot be set
properly. A new test case is also added. A slightly different patch will be
needed for branch-2 since HDFS-4949 is not in branch-2. I will post the
branch-2 patch once the trunk version is approved.
> WebHdfs compatibility broken between 2.2 and 1.x / 23.x

> Similarly to HDFS-5403, getFileBlockLocations() fail between old (1.x,
> 0.23.x) and new (2.x), but this is worse since both directions won't work.
> This is caused by the removal of "name" field from the serialized json format
> of DatanodeInfo.
> 2.x namenode should include "name" (ip:port) in the response and 2.x webhdfs
> client should use "name", if "ipAddr" and "xferPort" don't exist in the
> response.
